Automatic cold junction temperature compensation (Only thermocouple input type)
This detects the temperature at the connecting terminal between the thermocouple and
the instrument, and always maintains it at the same status as if the reference junction
location temperature was at 0 (32 ).
Burnout
When the thermocouple or RTD input is burnt out, PV display flashes “ ” (For
DC current output, OUT low limit value) with control output (OUT) being turned off.
When DC input is disconnected:
For 4-20mA DC and 1-5V DC input, the PV display flashes “ ”.
For 0-1V DC input, the PV display flashes “ ”.
For 0-20mA DC, 0-5V DC and 0-10V DC input, the PV display indicates the value
corresponding with 0mA or 0V input.
